PNPM: `pnpm install --fix-lockfile` broken

[ryan-roemer]

Trying to just run the following breaks:

 $ pnpm install --fix-lockfile
Scope: all 7 workspace projects
 ERR_PNPM_SPEC_NOT_SUPPORTED_BY_ANY_RESOLVER  [email protected][email protected] isn't supported by any available resolver.

This error happened while installing the dependencies of [email protected]
 at @webpack-cli/[email protected]
Progress: resolved 365, reused 247, downloaded 0, added 0

I've tried various package version changes for webpack and webpack-cli and nothing seems to work.

But, since pnpm install still works and updates pnpm-lock.yaml, we'll use that as a bandaid for our release workflow for now.
